Definitions
- This invention relates to a composition for softening fabrics and in particular to such a composition which is particulate and capable of imparting a softening benefit to fabric during a wash process.
- GB-A-1400898 Procter and Gamble suggests the use of smectite clays having a relatively high exchange capacity. While some fabric softening benefit can be obtained from detergent compositions containing fabric softening clays, this benefit is generally some way short of that which can be obtained by the application of softening materials to fabrics in the rinse step of a laundering process. Therefore, there is a desire to boost the performance of fabric softening clays in the wash.
- GB-A-2138037 (Colgate) proposes that the performance of fabric softening clays can be improved by the removal of grit therefrom and by their addition to the detergent composition as separate agglomerated particles.
- GB-A-1462484 Procter & Gamble proposes that in the presence of nonionic surfactants it is necessary to use smectite clays which have been rendered organophilic by an exchange reaction with quarternary ammonium compounds.
- GB-A-1400898 referred to above, is silent on the presence of nonionic surfactants.
- EP-A-11340 (Procter & Gamble) teaches that, in a composition which includes a mixture of a smectite clay and a tertiary amine for softening-in-the-wash, when anionic surfactants are employed it is preferred that nonionic surfactants be absent, but if mixtures containing nonionics are used, it is preferred that the anionic forms the major part of the mixture.
- the nonionic surfactant or mixture thereof which is essential to the present invention exists as a cloudy phase at 1% concentration in water at a temperature somewhere between 0°C and 15°C.
- the weight ratio of the clay to this nonionic surfactant system is from 2:3 to 20:1, preferably from 1:1 to 10:1. Any other nonionic surfactant material present which does not exist as a cloudy phase between these specified temperatures is not counted for the purposes of calculating the required clay to nonionic ratio.
- compositions of the invention may be in any particulate form, especially where the clay and the nonionic surfactant system are not in undiluted intimate contact with each other. More specifically however, this composition may be in the form of clay agglomerates which are formed of fine particle size clay, bound together with a material other than said nonionic surfactant system as a binder , or with no binder at all, the agglomerates carrying the nonionic surfactant system on the surface thereof.
- compositions may contain other ingredients, especially ingredients useful in the washing of fabrics. Alternatively, such other ingredients may be added separately. In either case a fully formulated fabric washing product may be obtained, and it is preferred that overall such products contain at least from 2% to 50%, most preferably from 5% to 40% by weight of a detergent active material, which amount includes the nonionic surfactant system associated with the fabric softening clay; from 20% to 70%, most preferably from 25% to 50% by weight, of a detergency builder material and from 1.5% to 35%, most preferably from 4% to 15% by weight of fabric softening clay material having associated with it the nonionic surfactant system.
- a detergent active material which amount includes the nonionic surfactant system associated with the fabric softening clay
- the nonionic surfactant system of the present invention exists as a cloudy phase somewhere in the temperature range of 0°C to 15°C, preferably 0°C to 10°C in distilled water at 1% concentration. In practise this means that the system has a cloud point of not more than 15°C, preferably not more than 10°C. Cloud point is a term well known in the art, for example from Surface Active Ethylene Oxide Adducts by N. Schonfeldt, Pergamon Press 1969, pp 145 to 154. In general terms the cloud point of a surfactant material is the temperature at which association between the surfactant and water molecules through hydrogen bonding breaks down, leading to the separation of surfactant rich and water rich phases and a consequential increase in turbidity or cloudiness.
- the cloud point correlates approximately to the hydrophilic - lipophilic balance (HLB) of the surfactant system and it is therefore preferred that the HLB should be less than 9.5, such as not more than 9.2.
- the HLB should preferably be above 6.0, most preferably above 8.0 to provide sufficient detergency.
- Suitable nonionic detergent compounds which may be used include in particular the reaction products of compounds having a hydrophobic group and a reactive hydrogen atom, for example aliphatic alcohols, acids, amides or alkyl phenols with alkylene oxides, especially ethylene oxide either alone or with propylene oxide.
- Specific nonionic detergent compounds are alkyl (C6 - C22) phenols-ethylene oxide condensates, the condensation products of aliphatic (C8 -C18) primary or secondary linear or branched alcohols with ethylene oxide, and products made by condensation of ethylene oxide with the reaction products of propylene oxide and ethylenediamine.
- Other so-called nonionic detergent compounds include long chain tertiary amine oxides, long chain tertiary phosphine oxide and dialkyl sulphoxides.
- alkylene oxide adducts of fatty materials are used as the nonionic detergent compounds
- the number of alkylene oxide groups per molecule has a considerable effect upon the cloud point as indicated by the Schonfeldt reference mentioned above.
- the chain length and nature of the fatty material is also influential, and thus the preferred number of alkylene oxide groups per molecule depends upon the nature and chain length of the fatty material.
- the fatty material is a fatty alcohol having about 13 to 15 carbon atoms
- the adduct having 3 ethylene oxide groups per molecule has a cloud point of less than 0°C and is therefore suitable for use in the present invention.
- a similar surfactant having 7 ethylene oxide groups per molecule has a cloud point of about 48°C and is therefore unsuitable. Further ethoxylation raises the cloud point still higher. Thus the similar surfactant with 11 ethylene oxide groups per molecule has a cloud point higher than 80°C.
- the clay containing material may be any such material capable of providing a fabric softening benefit.
- these materials will be of natural origin containing a three-layer swellable smectite clay which is ideally of the calcium and/or sodium montmorillonite type. It is preferable to exchange the natural calcium clays to the sodium form by using sodium carbonate, as described in GB 2 138 037 (Colgate).
- the effectiveness of a clay containing material as a fabric softener will depend inter alia on the level of smectite clay. Impurities such as calcite, feldspar and silica will often be present. Relatively impure clays can be used provided that such impurities are tolerable in the composition. In calculating the suitable clay to nonionic ratios however, it is the amount of smectite clay present which is important.
- compositions of the invention or the fabric washing products containing them, contain a detergent active material in addition to the nonionic surfactant system referred to above, this may be selected from other nonionic detergent active materials, anionic detergent active materials, zwitterionic or amphoteric detergent active materials or mixtures thereof.
- the anionic detergent active materials are usually water-soluble alkali metal salts of organic sulphates and sulphonates having alkyl radicals containing from about 8 to about 22 carbon atoms, the term alkyl being used to include the alkyl portion of higher acyl radicals.
- suitable synthetic anionic detergent compounds are sodium and potassium alkyl sulphates, especially those obtained by sulphating higher (C8 -C18) alcohols produced for example from tallow or coconut oil, sodium and potassium alkyl (C9 -C20) benzene sulphonates, particularly sodium linear secondary alkyl (C10 -C15) benzene sulphonates; sodium alkyl glyceryl ether sulphates, especially those ethers of the higher alcohols derived from tallow or coconut oil and synthetic alcohols derived from petroleum; sodium coconut oil fatty monoglyceride sulphates and sulphonates; sodium and potassium salts of sulphuric acid esters of higher (C8 -C18) fatty alcohol-alkylene oxide, particularly ethylene oxide, reaction products; the reaction products of fatty acids such as coconut fatty acids esterified with isethionic acid and neutralised with sodium hydroxide; sodium and potassium salts of fatty acid amides of methyl taurine; al
- compositions of the invention or the fabric washing products containing them, contain a detergency builder material this may be any material capable of reducing the level of free calcium ions in the wash liquor and will preferably provide the composition with other beneficial properties such as the generation of an alkaline pH, the suspension of soil removed from the fabric and the dispersion of the fabric softening clay material.
- phosphorus-containing inorganic detergency builders when present, include the water-soluble salts, especially alkaline metal pyrophosphates, orthophosphates, polyphosphates and phosphonates.
- Specific examples of inorganic phosphate builders include sodium and potassium tripolyphosphates, phosphates and hexametaphosphates.
- non-phosphorus-containing inorganic detergency builders when present, include water-soluble alkali metal carbonates, bicarbonates, silicates and crystalline and amorphous alumino silicates. Specific examples include sodium carbonate (with or without calcite seeds), potassium carbonate, sodium and potassium bicarbonates and silicates.
- organic detergency builders when present, include the alkaline metal, ammonium and substituted ammonium polyacetates, carboxylates, polycarboxylates, polyacetyl carboxylates and polyhydroxsulphonates. Specific examples include sodium, potassium, lithium, ammonium and substituted ammonium salts of ethylenediaminetetraacetic acid, nitrilotriacetic acid, oxydisuccinic acid, melitic acid, benzene polycarboxylic acids and citric acid.
- ingredients already mentioned may also be present, either as part of the clay containing compositions or as part of the overall fabric washing product.
- ingredients which may be present in the composition include the lather boosters, lather depressants, oxygen-releasing bleaching agents such as sodium perborate and sodium percarbonate, peracid bleach precursors, chlorine-releasing bleaching agents such as tricloroisocyanuric acid, inorganic salts such as sodium sulphate, and, usually present in very minor amounts, fluorescent agents, perfumes, enzymes such as proteases and amylases, germicides and colourants.
- Detergent compositions were prepared by spray-drying some ingredients to form a spray-dried base powder and then post-dosing the remaining ingredients.
- the approximate formulations were as follows:
- Example 1 the nonionic surfactant system in Example 1 consists of 1% A7 plus 3% A3 while the nonionic surfactant system in comparative Example 2 consists of 4% A7.
- Detergent compositions were prepared by post-dosing the following ingredients to the same base powder as used in Example 1:
- Example 5 Softness assessment was carried out as described in connection with Example 1, each composition being compared with that of Example 5, which contained no A3. The results were as follows:
